Speaker of the House Paul Ryan answers questions during his weekly press conference at the Capitol July 13, 2017, in Washington, D.C.

A so-called "sleeveless dress ban" in the lobby of the United States House of Representatives is likely to be slashed from the room's dress code after House Speaker Paul Ryan addressed controversy that bubbled up last week.

The controversy was kicked off by a recent CBS News report about the dress code in the Speaker's Lobby outside the House chamber, sparking a debate over whether the rules are rooted in sexism. Female reporters said they'd been told that sleeveless dresses are not considered appropriate, with one reporter attempting to cover her shoulders with notebook pages, according to CBS News.

On Thursday, Ryan said he valued decorum in the House but said he's working on changing it to adapt to modern-day dress.

"Decorum is important, especially for this institution. And a dress code in the chamber and the lobby makes sense. But we also don’t need to bar otherwise accepted, contemporary business attire. So look for a change on that soon," he said.

The move has women, from female Capitol reporters to Minority Leader Nancy Pelosi, celebrating "the right to bare arms," as the dress code is likely to take new styles in men's and women's fashion into account.

Glad to see @SpeakerRyan is updating the dress code for the House Floor. These unwritten rules are in desperate need of updates.

Jennifer Lawless, a professor of government and director of the Women & Politics Institute at the School of Public Affairs at American University, said that what is considered "appropriate" for men and women varies, and has changed over time.

"The rules have become irrelevant," Lawless told NBC last week. "Just because women are wearing sleeveless tops does not mean they're dressing inappropriately…To suggest that they have to dress in a particular way constrains their choices in a way that men are not."
